GENERAL DESCRIPTION
The OP777 , OP727 , and OP747 are precision single , dual,
and quad rail-to-rail output single- supply amplifiers featuring
micropower operation and rail-to-rail output ranges. These
amplifier s provide improved performance over the industry -standard
OP07 with ±15 V supplies , and offer the further advantage of true
single -supply operation down to V , and smaller package
options than any other high-voltage precision bipolar amplifier.
Outputs are stable with capacitive loads of over 500 pF. Supply
current is less than 300 μA per amplifier at 5 V. 500 Ω series resis-
tors protect the inputs, allowing input signal levels several volts above
the positive supply without phase reversal.
Applications for these amplifiers include both line-powered and
portable instrumentation, remote sensor signal conditioning, and
precision filters.
The OP777, OP727, and OP747 are specified over the extended
industrial (–40°C to +85°C) temperature range. The OP777,
single, is available in 8-lead MSOP and 8-lead SOIC packages.
The OP747, quad, is available in 14-lead TSSOP and narrow
14-lead SO packages. Surface-mount devices in TSSOP and MSOP
packages are available in tape and reel only.
The OP727, dual, is available in 8-lead TSSOP and 8-lead
SOIC packages. The OP727 8-lead SOIC pin configuration
differs from the standard 8-lead operational amplifier pinout.
